GINNINGAPPARATUS.

SPECIFICATION forming part of Letters Patent No. 734,696," dated July 28, 1903 Application filed April 18, 1902 To all whom it may concern:

Be it known that I, J AMEs T. FULLER, a citir porting and holding the points in position,

and of a novel construction of the cylinder or drum by which the points are carried.

The invention consists of the improved devices and features of construction and "arrangement herein described and claimed.

In the drawings, Figure 1 is an elevation, partly in section, showing aginning-cylinder embodying my invention with parts broken away. Fig. 2 shows two partial sections of 2 5 the cylinder on a larger scale, and Fig. 3 is a detail illustrating my improved ginning-point and the preferred manner of securing it in position. g a

This invention, while not restricted thereto, is particularly adapted for use in my improved ginning apparatus, for which I have filed an application for United States Letters Patent, Serial No.73,117, filed August 24, 1901.

The preferred form of apparatus embodying my invention which I have selected for illustration and description comprises a pluf ralit-y of ring-like sections 1, which are do plicates of each other and which are carried by, but are not directly secured to, the shaft 2, upon which is mounted in the usual mannor the driving-pulley 3. 1 Each ring-section 1 is on one side provided with slots or grooves 4, Fig. 3, which receive the pin-like ginningpoints 5, which extend in circumferential alinementaround the ginning-cylinder. Each ring-section is also provided with a step or projection 6, upon which the adjacent section rests and by which it is supported in concentric relation with the shaft 2. To the Serial No- 103,564. (No model.)

of the cylinder; but these sections 10 are secured to the shaft only by a spline 11, which enters a groove formed in the hub of each section, so as to permit the section to move longitudinally on the shaft while securing it rotatively thereto. The ring-sections 1 are held in rotative relation to the shaft by means of bolts 12, which pass through lugs 13 on the rings 1 and through the webs of the sections which are fixed to the shaft. At the ends of the cylinder the bolts 12 pass. through the heads 14, which are splined to the shaft and are clamped against the end ring-sections by the clamping-nut 15, which is held in position by the lock-nut 16.

In the particular form of apparatuis shown in the drawings, Fig. 3, the ginning-points 5 are in the form of pins, curved at their upper or working end toward the direction in which the shaft2 rotates, while the lower end, which .80 I have for the sake of brevity called the holding end, which lies below the surface of the ginning-cylinder, is bent forward in the same direction, so as to form a bend or elbow which lies inthe grove 20 between the two rows of 8 pointreceiving slots or grooves 4. It will thus be noted that when the points are in position and the face of the adjacent ring covers the point-receiving grooves 4 the points are held securely in place by the bend in the points, which prevents them from turning and from being drawn lengthwise .from the slots, and one of the important features of my invention is the shaping of these ginningpoints,asbybendingthemintotheformshown 5 or into some equivalent form, so that they will thus be held securely in operative position without necessitating, so far as operative conditions are concerned, the employmentofanypermanentrigidfasteningmeans; I00

but for convenience in assembling or disassembling the parts of the cylinder I prefer to provide some means for preventing the points from falling out of the open-sided grooves when the ring is not in position, but which will not interfere with the ready removal of the points when the sections are separated. For this purpose the space between the points and the sides of the grooves may be filled with some substance like rubber-cement as soon as the points are placed in position, or any other suitable temporary and easily-disengaged retaining means may be employed.

To secure the desired frictional effect between the surface of the cylinder. and the material being operated on, I prefer to cover the operative surface of the rings with some suitable substance 21, such as leather or rubber cement, and I also in the form of the apparatus illustrated reduce the diameter of each ring, as at 22, so that when the rings are assembled a series of circumferential grooves will be formed in the face of the cylinder, one adjacent to each row of points.

As will be observed, each point-carrying ring or sections supports an adjacent pointcarrying ring, thus securing compactness of construction, and each ring also-holds the points of an adjacent ring in the grooves of that ring. A uniform elevation of the ginning-pointsis secured by permitting the lower ends of the points or pins to rest on the step 6, which supports the next ring.

In Fig. 3 I have illustrated the arrangementof point-receiving grooves which I prefer to employ. In this construction the side of the ring on which the points are carried is provided with a circumferential channel 20, which in effect forms two projecting flanges 23 and 24, and in thesefianges are formed the point-receiving grooves 4, the grooves in one flange extending obliquely to the grooves in the other flange. Besides the saving in weight thus eifected this construction enables me to form thepoints without an abrupt bend and still to use straight grooves, which can be economically and accurately formed at comparatively slight expense. For these reasons, among others, I consider this arrangement preferable; but it is to be understood that my invention is not restricted to the specific formation of the ginning-points or to the particular direction and form of grooves illustrated, since it is only necessary that the holding or lower portion of the points should be provided with a bend or curve great enough to prevent rotation and that the curve or the approximately straight sections of that portion of the points which are united by the curve should extend in different directions or be irregular in conformation to prevent withdrawal endwise, and these requirements secured the grooves may be ofany shape or may extend in any suitable direction which will receive and support the correspondinglyshaped points in the manner described. Thus some portion of each groove if it be a continuous one extending from the inside to the periphery of the ring or the grooves of either the inside or outside row if the grooves be divided into two concentric rows, as shown in Fig. 3, should extend in a direction which would be intersected by a radial line drawn through the groove from the axis of the ring.

By the term line of varying direction, which I have used herein, I intend to cover all these and other equivalent variations in the arrangement and disposition of the pointholding grooves.

In the apparatus illustrated in the drawingsthe shaft-engaging section 7 is shown as carrying ginning-points on both of its sides, and the ring-sections are shown as facing each other. This is for the purpose of securing a symmetrical arrangement of the parts and when employed in connection with my improved gin shown and described in my said pending application causes the longitudinal thrust on the two ends of the cylinder to be perfectly balanced.

The beneficial advantages of my invention are numerous and will be apparent to any one skilled in the use or manufacture of this class of apparatus. Among other advantages not heretofore mentioned are the ease with which broken or worn points may be re placed, the great saving in weight, the fact that all parts are duplicates and interchangeable and can be cheaply made with minimum amount of machine-work, the slight cost of separate parts, and the ease with which repairs and replacements can be perfectly and expeditiously made by unskilled labor.
